On Aegean Airlines, the "Oriental Vegetarian" meal option is literally just a few raw vegetables covered in plastic wrap.

Unless you're lucky enough to be flying first class, one of the most disappointing parts about traveling is mediocre airplane food. But some airline meals transcend the realm of "mildly bland and soggy" and reach a territory that's almost hilariously inedible or inadequate. We rounded up photos of the saddest airline meals that people were actually served.

From dietary restrictions requests gone wrong, to completely unidentifiable sandwich fillings, you can count your lucky peanut packets if you never had to experience these inflight foods.

The "Oriental Vegetarian" meal from Aegean Airlines

It's really tough having a dietary restriction onboard an airplane. Your options are usually limited, but this particular vegetarian "dish" is just downright insulting. This pile of raw vegetables wrapped in plastic wrap was served on-board the Greek Aegean Airlines. As Reddit user Musterknabe explained in his June 28 post,"the 'oriental' part was apparently the Chinese celery." He later requested an extra cookie for his trouble.

The "mystery meat" burger from North Korea's Kyoto Airlines

What this burger is made of is a mystery, but this questionable burger patty coupled with a limp lettuce leaf and soggy cabbage is the only food option onboard Koryo airlines, and always served cold.

Ham and cheese "sandwich" from Transavia Airlines

We're honestly more puzzled than disgusted by this square Lunchable masquerading as a "ham and cheese sandwich." As Twitter user Ellis Pisters says, "had no choice." Transavia airlines is a small budget Dutch airline owned by Air France.

This sandwich from Delta Airlines

Another sad sandwich makes the list. This vegetarian meal served onboard a Delta flight from Dublin to JFK consists entirely of two slices of tomato, three cucumbers, and a slathering of ketchup. To be fair, the tomatoes actually look really fresh, but we doubt this would fill anyone up.

A banana with a knife (gluten-free breakfast) from All Nippon Airways

This inflight food faux-pas made headlines for being laughably ridiculous. On a nine-hour flight from Tokyo to Sydney in May, London resident Martin Pavelka complained that when he asked for a gluten-free breakfast, he received only a single banana and a knife and fork. All Nippon Airways was forced to apologize. Apparently there was a mix-up: the solitary banana was meant to be a snack and not a full meal.

Didn't anyone ever tell you to never order the fish on a plane? This supremely sad tuna sandwich ordered on a flight from Slovenia to Albania was described by its recipient as "bread seasoned with tuna." It looks like there might be some cheese globs on the roll as well.
